By number of atoms it has more hydrogen, by mass it has more oxygen. Each water molecule contains two hydrogen atoms and one oxygen atom. However, a typical oxygen atom has about 16 times the mass of a typical hydrogen atom.
Electron.
Generally, hydrogen peroxide bottles contain 1 to 3% peroxide.
Hydrochloric acid or HCl, is an acid because the bond between the hydrogen and chlorine atoms can break, in this case very easily. When this happen the hydrogen atom leaves being its electron and becomes an ion. An acid is a substance that can release a hydrogen ion in such a matter.

In the vicinity of 11 gallons is typical.
Hydrogen burn in air releasing a typical sound.
There are many ozone forming components in an office. Air conditioners are one of them.
I believe that typical rates as of 2010 are in the vicinity of $300 per hour.

Trees grow from the ground. The ground is often lower than a plane. If the plane is lower than the ground, the passengers and crew are having a very bad day. Since the typical plane that is flying is flying higher than the trees in the vicinity, it is safe to conjecture that the air pressure around a typical tree is higher than the air pressure around a typical plane flying in the vicinity of those trees.
